A better question is, why does "module-usb_keyboard.mod" exist in the
first place? In theory, GRUB should be able to use whatever the
firmware provides to access key presses and shouldn't need a module at
all.

However, there were a few incredibly dodgy computers (mostly "late
1990s" time frame?) where the firmware expects a PS/2 keyboard and
firmware's keyboard support doesn't work with a USB keyboard. GRUB
probably provides a "module-usb_keyboard.mod" so that USB keyboards
will work properly on these incredibly dodgy computers.

Note: I'm not a GRUB developer or anything, I just know how much
computers can suck. ;-)
